How To Car Wire A Jump Edible Bean From A Jsf Managed Edible Bean Inwards Liferay Portlet

There are ii ways I know to auto-wire a saltation edible bean into a jsf managed bean:

1.) Is through WebApplicationContext, invoke during jsf managed edible bean constructor:

Below are the near vital files to perform this action:

web.xml

<?xml version="1.0"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">   <context-param>   <param-name>contextConfigLocation</param-name>   <param-value>WEB-INF/applicationContext.xml</param-value>  </context-param>   <listener>   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <listener>   <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>  </listener>   <servlet>   <servlet-name>Faces Servlet</servlet-name>   <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>   <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>   <servlet-name>Faces Servlet</servlet-name>   <url-pattern>*.jsf</url-pattern>  </servlet-mapping>  <servlet-mapping>   <servlet-name>Faces Servlet</servlet-name>   <url-pattern>/faces/*</url-pattern>  </servlet-mapping>  </web-app> 

Take banking concern notation of the added listener for spring. applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"  xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"  xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context-3.0.xsd  http://www.springframework.org/schema/jee  http://www.springframework.org/schema/jee/spring-jee-3.0.xsd  http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"  default-autowire="byName">   <context:annotation-config />  <context:component-scan base-package="com.ipiel" />  <tx:annotation-driven /> </beans> 

faces-config.xml

<?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"  version="2.0">   <application>   <variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>   <!-- <message-bundle>i18nFaces</message-bundle> -->   <resource-bundle>    <base-name>com.sido.resources</base-name>    <var>msg</var>   </resource-bundle>   <locale-config>    <default-locale>en</default-locale>   </locale-config>  </application>  </faces-config> 

portlet.xml

<?xml version="1.0"?> <portlet-app version="2.0"  xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd">  <portlet>   <portlet-name>czetsuya</portlet-name>   <display-name>czetsuya@gmail.com</display-name>   <portlet-class>org.portletfaces.bridge.GenericFacesPortlet</portlet-class>   <init-param>    <name>javax.portlet.faces.defaultViewId.view</name>    <value>/view.xhtml</value>   </init-param>   <init-param>    <name>javax.portlet.faces.defaultViewId.edit</name>    <value>/edit.xhtml</value>   </init-param>   <supports>    <mime-type>text/html</mime-type>    <portlet-mode>view</portlet-mode>    <portlet-mode>edit</portlet-mode>   </supports>   <portlet-info>    <title></title>    <short-title></short-title>    <keywords></keywords>   </portlet-info>  </portlet> </portlet-app> 

Now let's await at the saltation edible bean in addition to jsf managed edible bean classes:
The saltation edible bean service class:

@Service world aeroplane IpielService {  static in conclusion Logger log = LoggerFactory.getLogger(IpielService.class);  @PersistenceContext   protected EntityManager entityManager;   world List list() {   List lawsuit = entityManager.createQuery(     "SELECT a FROM MyModel a").getResultList();   provide result;  } } 

And the JSF managed edible bean

@RequestScoped @ManagedBean world aeroplane IpielAction implements Serializable {   soul IpielService ipielService;    world DeviceManagerAction() {   WebApplicationContext ctx =  FacesContextUtils.getWebApplicationContext(FacesContext.getCurrentInstance());   ipielService = ctx.getBean(IpielService.class);  } } 

Noticed that nosotros need to buy the farm the ipielService saltation edible bean from the context to last able to inject into a jsf managed bean.
2.) Using @Autowired annotation from spring. We volition role the same configuration files every bit above, in addition to produce to a greater extent than or less changes on IpielAction. Actually nosotros only need to take away the constructor in addition to add together @Autowired annotation inward ipielService

@RequestScoped @Component world aeroplane IpielAction implements Serializable {   @Autowired  soul IpielService ipielService;  } 

JSF should last able to locate IpielAction because of the variable resolver we've specified inward faces-config.xml. Take banking concern notation that we've changed @ManagedBean annotation into @Component to last able for saltation to encounter it.
